A California petcoke facility used wastewater ion exchange to remove nickel and vanadium from stormwater leachate, ensuring compliant discharge and reliable, scalable treatment of accumulated rainwater.

Green hydrogen may be one of the keys to sustainably meeting our future energy needs, but one often overlooked aspect of effective electrolysis and hydrogen production is water purity.

A refinery in Northern California was unable to meet its desired boiler feed water silica specifications on a consistent basis. The higher silica levels led to an excessive blow down requirement in the boiler system. The higher blow down rates were significantly affecting the refinery's water, chemical, and natural gas costs.

An oil refinery in the US Midwest scheduled repairs to an existing wastewater treatment system. Refinery operations needed a temporary treatment system on site to maintain uptime during the outage.

In mid-2015, a chemical plant located along the Gulf Coast experienced an emergency chemical spill which upset their treatment processes. The company reached out to Evoqua Water Technologies with an urgent need to treat wastewater that had been contaminated by a chemical release at their site.

A West Coast refinery turned to Xylem for help in providing a more consistent and reliable quality of purified boiler feedwater. The refinery, using up to 1,500 gpm of demineralized boiler makeup water, was experiencing a variety of problems including aging demineralizers, pending environmental legislation, excessive operation costs, wide variations of raw water quality, and limited capital to address these issues.

A Gulf Coast chemical plant was faced with an unreliable demineralizer system to meet a proposed expansion of boiler feedwater requirements. In addition, the plant had a wastewater goal of zero liquid discharge. High total dissolved solids (TDS) in a proposed new well-water source threatened to increase demineralizer regeneration frequency, greatly increasing acid and caustic usage.

A Southern California refinery resolved stormwater discharge permit violations in five days using Xylem’s vessel-based treatment system with organoclay, carbon, and ion exchange to remove hydrocarbons and metals to ppb levels.
